Move settings.db file from old phone to new

Just a quick question for all the super users out here. I currently have a captivate that is rooted and sideloading enabled. Due to speaker issues it is being replaced after rooting my new phone ( from ATT ) what would happen if I copied my current settings.db file over to the new phone? Would this cause issues? I know I could just redo the sideloading part but I am curious.

Assuming you are going to be running the same setup you should be fine.

I own an Evo, so I don't know much about these.. but can anyone confirm if this would work?
1. make nandroid backup of old phone
2. root new phone
3. install clockwork recovery on new phone
4. make nandroid backup of new phone
5. restore nandroid backup from old phone
I know this works on an Evo, but on the Evo you have to use amen ra recovery so you don't restore your old 4g RSA keys. Does the Captivate have any device specific files that cannot be transferred between phones? If not, I don't see why this wouldn't work.

i dont know if it causes trouble but i have 2 phones and the setting file is different on each one so it might have some problems if the wrong thi ng is change

[Q] need help with efs

happy new year to everyone.
I've just bought nexus s gt i9020 in U.K
Ginger 2.3.1
grh78
baseband i9020xxjk8
I'm going to root and install clockwork via ONE-CLICK-ROOTon it and I have one question ;
When should I backup my eds folder, before or after is rooted ?
thank u in advance
if any one of u bought recently the same nexus s from carephonewarehouse and already made all steps(rooting, clockwork, new room) and want to advice me, I'll really appreciate this

As soon as you make backup, safer you are..

but should/can I backup it before rooting and installing clockwork?
ok so ill root phone, then install clockwork and then run eds tool to backup folder, is that correct?

If you can back it up via adb do it as soon as possible, not sure if you actually need root for this. I believe you'll be wanting a copy with set permissions (so archive it as a .tar.gz file, which stores this data), and a raw translation of the device it is mounted under.
I personally got all my info from here, and happily so far have never had to even think about going through my backups. All worked fine (though it takes a while for the RAW to copy over).

thanks mate for help

[SOLVED] Efs?

What is it? Because I want to download the mokeeOS, but the installation is confusing me, so I wanna know if the efs matters

1. Yes efs matters a lot
2. I don't know a whole lot but it holds the network info, imei number, and alot of other really important things

Although there is a way to make sure you have a backup, flash this file in cwm
sourceforge.net/projects/teamacid/files/fb/cwm/cm7-efs-backup.zip/download
And there will be two files in the root of your sd card
Efs-backup.tar and efs-backup.tar.md5 ( I suggest save it to your computer, it saved my ass )
And you can restore this backup at anytime by flashing this
sourceforge.net/projects/teamacid/files/fb/cwm/cm7-efs-restore.zip/download
Good luck

Efs is the files system that holds the unique identifiers for your device. Without it, your phone is basically useless. You won't be able to connect to any network properly do things like phone calls, internet, texting, are all degraded, if they even work at all... Make sure you know what you are doing before messing with it. Fb created a vet good guide on the wiki. Follow it to a T!

I would suggest using a root browser to copy the EFS folder to somewhere safe on your PC and copy a 2nd back-up to your SD card. I lost IMEI going from CM7 to moKeeOS but was able to easliy restore it with a back-up and a root browser.
The flashable EFS back-up/restore from FB should still be used, but with EFS/IMEI I don't think you can be too careful and backing it up manually as previously stated is a good idea.

Yeah, I keep multiple copies of it on my PC. The reason being is that I copy it whenever I do a backup before a flash. So I have a directory with the date with 3 folders: efs, nandroid, and sdcard. I used adb to copy them:
Code:
cd efs
adb pull /efs/
Probably overkill, but better to be safe than sorry, eh?

Ok, but once you lose IMEI and don't have a backup (I received this phone for repair), then what can I do?

It's pretty much screwed without the OEM Samsung/Tmo software. You would have to send it to Samsung for repair, or you might get lucky and get an engineer to hook you up, but that is unlikely...

thanks for the answer. that OEM software isn't available in the forums or anywhere else for us? because I swear I flashed something OEM'ish without root with heimdall.
also, the imei is on the battery part of the phone, can't i fix it?
i read somewhere that you could use a phone just fine without imei on the about phone.

you can use the phone without imei, but it doesn't function as well as it would with it. Also, i was using titanium backup and it said my device's id was changed, and it showed my actual imei. If i were to restore it, would that fix the imei?

EFS help on the SGH-T959V
Basically, I've had a hell of a time with some EFS drama this weekend, made a total noob mistake, but in a stroke of luck I was able to "recover" so to speak my EFS even after it was supposedly "wiped."
After some thorough research and READING and bit of thought, I realized that the PIT mapping layouts between BML and MTD are indeed different, and that in theory if one remaps to BML (in layman's terms a stock partition map) then the EFS data originally on the phone gets correctly remapped (at least in my case it did).
To reiterate:
1. I did a nandroid backup. Basic ****. I hope to god you at least did this step too.
2. I used the cm7-efs-backup.zip script to backup my EFS. This was my first mistake. In my case, I don't know why I'm still researching, this script failed to make a backup .tar on my sdcard or anywhere else for that matter. It didn't throw any error messages either on the screen in the process. Not trying to attack the authors of that script, I'm just saying it didn't work for me this time.
3. I pushed the TWRP boot.img with Heimdall
4. I used the cm7-efs-restore.zip script which also "succeeded" but did nothing to restore any sort of EFS obviously because there was no backup to begin with.
5. I flashed R11 unofficial cm7 and booted up. Everything was fine but the IMEI was corrupted and I confirmed that the new MTD EFS partition was empty. On T-Mobile I could place no calls and only got sporadic and intermittent data access.
It was at this point I was sure I had ruined my phone.
After some more careful reading I realized that the original EFS was still present on the firmware, however the new MTD layout I flashed (wisely) stores its EFS partition in a different physical location. In theory, I thought if I reverted to BML and a stock ROM then I would recover the original EFS. In my case, this was successful.
1. I accessed the most recent "boot.img" file from my most recent nandroid and pushed that back to the device with Heimdall
2. At this point you have to flip your USB drivers back to USB Composite Device.
3. I then used a Heimdall one click to return to a rooted stock KJ6 "Gremlin Remover"
4. Upon restart, everything was fine (sigh of relief)
At this point, I'm still trying to determine why my EFS cannot be backed up with a few automatic tools. I made a backup of the file structure, but even lyriquidperfection's EFS Pro 1.4.7 can't make a backup of the EFS. It can access the ADB Server, but the backup 'fails'.
I'll check back in after I figure out why.
Hopefully this info will help anyone else who has switched to MTD and has a missing EFS.

I had similar issues yesterday. If your trying to install the twrp and then downgrade to the version with wifi dont flash the boot.img with heimdall. Follow the instructions for installing via cwm.
Just install the zip that has twrp in it. But follow the directions for normal cwm installation.
Also when trying to make a backup of your efs, make sure system is mounted. I initially did not have any problem but I was on antonx's kernel and when you flash with that recovery it would mount properly. What is happening is system isnt getting mounted. So its making a null backup.
The most important thing to do is when you are trying to make a backup of your efs is mount system!

Hi have you tried the updated EFS Pro v1.7.13? It can now automatically detect the mount point of the '/efs' folder for back up and restore. Also many many bug fixes and new code to communicate with adb.exe alot more quickly and efficiently.
Head over to the forum and check it out.

I already solved this problem, but this would seem useful other people with the same problem. But what forums are you exactly referring to?

Mention of EFS/No register network

For the last two months i was trying to restore IMEI number in S3 19300.. I didnt have backup.
i tried more even 10 stocks+modem vers / ARIZA patch and more more..
finally i took it to Lab for reburn the IMEI by box.
Until here all right ?
I took a another different S3 smartphone and wanted to replace Rom,so i backuped by using some applications the EFS( i have 5 backups of efs right).
1.i installed the new Rom.
2.IMEI changed to 0009.
3.so i just backup the efs folder (used one of the 5 backup) and flashed last modem like in the old stock rom+set apn manual
4.IMEI has back to the original but still cant take out Call or Message i got message NO REGISTER NETWORK
5.tried other backup and still same problem.
Now I'm the conclusion which it opened the discussion.
one of the backup was by app called Partitions Backup & Restore https://play.google.com/store/apps/details?id=ma.wanam.partitions
the backup made 2 files one EFS and on Radio .img.
after 4 hours of break the brain i flashed the Radio.img and suddenly i was able to get out Calls and messages.:good:
why most the guides of backup IMEI dont mention the backing of the radio folder?
Thank you.

NVData / EFS issue / already created backup, verify image?

Hi,
I have a note 3 neo, 7505 and i updated the firmware. It was all working good for a week then i was listening to soundcloud to sleep and the phone restarted, since then the phone doesn't have an imei and says to insert sim card, and of course unknown modem..
Anyway, i created a backup of the efs using twrp, i have tried gazillion ways to restore the backup and gazillion manual ways too. Going to stock recovery... trying to copy manually the nvdata and all but it doesnt resolve. The files are placed there, i can see it in the shell but the thing just wont work!
i don't know how to proceed to this, i don't know if its a hardware fault, had it been that, shouldnt have i gotten the efs corrupted or some issue? could it be that the hardware itself is damaged all of a sudden? i dont think so, i pretty much think its the efs and yet i cant restore it?
should i attach my efs folder if someone can look through hex editor or logs to suggest a possible solution?
Thanks a lot and also i have search through and proceeded with many solutions and after that created a thread. hope someone can help.
P.S. I just noticed the serial number can be seen in phone status, so apparently its reading NVdata? or is it getting it from elsewhere? how to test if its a hardware fault?

The point is that TWRP creates faulty EFS backups on many devices which can't be restored properly.
There are different backup solutions (e.g. EFS Pro) confirmed working which may help you prevent future issues. I prefer the manual backup using adb shell or terminal emulator:
dd if=/dev/block/mmcblk0pXX of=/storage/SdCard/efs.img bs=4096
(XX needs to be replaced with the model specific partition number as they use different partition tables)
Restore:
dd if=/storage/SdCard/efs.img of=/dev/block/mmcblk0pXX bs=4096

thanks LS.xd, but i guess i have a pretty solid backup as i did create backup various ways, some were corrupt, but one that i working with has nvdata and every other file along with imei pretty intact....
i can open it up with winrar, and open the nvdata with hexeditor, i was wondering if i could confirm some way that the back up is actually 100% solid?
wondering if the partition's aren't aligned. I don't know for sure if EFS folder in the root directory is the same as being pointed by /mmcblkp03/platform/by-name/EFS ?
i mean they should be the same thing, its just a redirection right?
what should i be doing now? the baseband is unknown and the imei wont just work, waste the phone? or it could be done via some boxes or some other process?

there must be a starting point? isn't there some way i could use a generic imei and just any modem? then i could replace nvdata may be? right now, i'm installing various versions of stock firmware and repeatedly placing old efs data in various ways and i kind of turning hopeless. first i lost a nexus then i bought a g4 last month, gave me a bootloop just a week after, gone dead. then i bought the n3n and now this..... i mean 3 phones in a row..... i really hope this could work..

So you got some non TWRP made EFS backup, too? You can list your partitions using shell:
[email protected]:/ # cat /proc/emmc
You can use the dd command once you know the layout. Backups not generated manually may only be restored with the specific app/version and are probably not compatible using other restore methods. For my OnePlus 3 EFS backup can generated fine using TWRP but restoring it screws up the partition. Manually created image works fine. As I don't have a Note 3 Neo I don't know how it behaves for your device.

any idea how would i go on about inspecting the nvdata.bin? i'm in hex editor trying to see something resembling imei but its just so much garbage except a few lines.
i can't be sure whether its corrupt or not...
in efs -> imei -> a file called mps_code.dat i open it up in hex editor, and it has only 3 characters.....
is it possible i could initially use a generic imei and modem and later on populate it with actual somehow or just keep using generic one for now until i find a better solution, using hex editor or something...?
there are some tutorials on qualcom.. none for exynos but it should happen the same way, somewhere in nvdata, you place the imei ... and it would be generic method for most exynos devices...
i wish someone could guide me to that...
also can it be restored via "boxes"?

After 3 years I had to retire my HTC One S. I flashed roms and firmwares up to 3-4 times a week without having any issues. One sunny day some update bricked then nvdata. I spent a bunch of hours trying to restore it in different ways, extracted data from stock firmware as well as using dumps from other user's phones, as some users reported this error fixed doing so. Even when the files was identical it just did not work for me. Changing the mainboard was the only possible solution so I decided to get a new device.
All I want to say is try to restore a valid backup in a way confirmed working. If you don't have a usable backup ask in your device's forum for somebody may upload it. Or spend 100 hours messing around with hex editors until you reach then point where you realize its cheaper to switch the device as wasting a year's holidays browsing the internet for some solution.
